The geologic conditions in the foundation of the Geheyan gravity arch dam on the Qingjiang River are complicated.In the foundation,there are numerous weak intercalations and fractural textures,and developed karst erosion.There are locally unstable rock masses in the abutments.During dam design,many schemes of foundation treatment were considered.Through comprehensive comparison,the treatment scheme of using the concrete slide preventing keys and columns to stablize the unstable rock masses was adopted.The plane FEM was used for analysing the displacements and stresses in the dam and the dam foundation before and after dam foundation treatment.Analysed results show that the above mentioned treatment scheme is appropriate.Through this analysis,it would be considered that the plane non linear FEM is rational for studying problems about the deep stability treatment of arch dam abutment.

清江隔河岩重力拱坝坝基地质条件复杂,软弱夹层、断裂构造多,岩溶发育,两岸拱座存在局部滑动问题。设计中提出了许多基础处理方案,经综合比较确定对不稳定块体采用混凝土阻滑键和混凝土传力柱阻滑处理方案。应用平面有限元法对坝基处理前后坝体和坝基的变位和应力进行了计算和分析。分析表明:上述处理方案是合适的。通过本项计算分析,认为采用平面非线性有限元法研究拱坝的拱座深层稳定处理问题是合适的。
